New Insights into the Mechanisms of Spontaneous and Base-Catalysed Substitution Reactions of the Inert Metal Amine Complexes

摘要: Abstract For Co(III) amine complexes, there is a large body of evidence that points to spontaneous substitution reactions occurring via interchange mechanisms in which bond breaking substantially precedes making the transition state. The Rh(III), Ir(III), Ru(III), Os(III) and Cr(III) analogues depend very much on number factors, such as nature leaving group steric well electronic configuration metal ion. On balance evidence, d3 d5 complexes can proceed either or vice versa. [M(NH3)5Cl]2+ ionic solvation terms [M(NH3)5]3+ Cl- components with respect strongly favor state substantial charge separation, i.e., dissociative are energetically more accessible than a...
